To all whom it mag/concern:

Be it known that I, MAnin D. Ananke, a citizen of the United States, residing at Lawton, in the county of Ramsey, vState of North Dakota, have .invented certain new and useful Improvements in Envelope; and I do hereby. declare the following tobe a fu clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new anduseful improvements in envelops.

The primary object ofthe invention is to forni the envelop of 4a blank of no vel formation and which can be stamped from sheet material', the invention being'especially designed for producing a box like envelop whereby increased packing space is provide lfor the sending of parcels or articles of merchandise through the mails.

Another object of the invention is to construct anenvelop havingconsiderably more vpacking space than an ordinary 'envelop and also toprovide novelmeans for holdingthe Venvelop closed.

With the above andother objects in view,

the invent-ion consists' in the. combinations.

and arrangements of parts to be hereinafter more clearly described, claimed and illustrated in the 'accompanying drawings,l in

which Figure 1 is ya perspective vievy of my improved envelop sealed ready for use.

Fig. '2

'is' a perspective view of the envelop with the closing iap :in a raised position land showing the envelop slightly collapsed be# Vfore beingsealed. yFig. 3 is a vertical sectionalvie'wof the envelop; Fig. f1 isa plan .View of a blank fromgwhicli'the envelop is formed. Fig. 5 is a longitudinal sectional view of the envelop. Fig. 6 is anenlarged detail view of fastening eye or plate carried by the closing flap. Fig. Tis a similar view of a tongue carried by the-. .front portion of.

and holding. the envelop closed.

-Referring to the drawings in detail there is shown my. improved envelop which is formed of a blank section ofinaterial suitably stamped from aslieet of paper oithe like and comprising a front portion and 55` lower edges. The bottom portion V12l is speciacatifm of Letters raten;

'back portions thereof.A

late

llmatented dpr.

bottom andftlicse tonguesare formed with a central. longitudinal crease or weakening line 14 forming a folding line for'the 'bottom' adapted to be extended inwardlyrbetween'fthe lfront and back portions so that they will'be formed at its end with tongues andthe mum amount of space when.v packed. The backvportion 11 is formed with integral side flaps 15 whichare adapted' to'benjd 'for- Wardly along the folding lines 16 andi. each of these side flaps 15 i'sforined witlifa supplemental flap V-17 bentv along the folding lines 18' parallel to the lines 16 andv said flaps 1f? are covered with a suitable adhesive substance by which they are secured to the .inner face of the front portion ofthe envelop vertically of` its side portions and thereby form a bon like structureorrecep- 'tacle- The tongues 13 are then bent along theA folding lines 1,9 which are disposed contiguous ,with the folding lines 16 and are covered with a suitable adhesive substance on their inner faces by 'which they are -secured to the outer faces of the side flaps 15 neai` their lower ends.' By this construction the central longitudinal crease'or weaken` ing line '14 will lie coincident with a central 'l vertical crease or weakening line 2O in eachlofthe side lia-ps 15, 'with respect to the .por-V tions of said line 14 which extend through upwardly and secured tothe side 'flaps and when the envelop is folded along the lines 14 and 20 the upper. ends of the side flaps 15 will fold downwardly along the inclined folding lines 21l extending from the upper corners ofthe side flaps 15 to the central folding lines and at right angles to each parallel to the upper edges of the frontl and:

The back-port` on 1 1 is formed with a top the tongues 13 when the latter are folded v eov orv cover flap 23 whichisfoldable down#y wardly along the line Qlvto closetlie top of theenvelop .and this flap 23 is formedY with a sealing or closing nap 25 which is bentf along the line 26 and is' coated with a suitable adhesive su whereby' it 'may face on the front por lon .Il if desired. The' toptlap 2351s also-f-ormedwith side flaps or tongues 2'? whichv Vare .foldable along the lines 28 coincident with the folding lines 165 e an its inner face` .terriedto the .outer v 'rectangular form except. that it has corner prongs 30 forming an approximately starshaped member and said prongs are extend ed through the closing flap and rebent if de# slred to secure the plate against the outer face of said flap. The plate 2) is further provided lwith a central opening 3l disposed ,over a corresponding opening in the closing or sealing flap and engaged by the free extremity of a securing tongue 32 which has its opposite extremity formed with an end prong 33 and side prongs 3l which are extended through the front portion of the envelop adjacent its bottom edge so that the free end of the tongue will extend upwardly and when engaged through the plate 29 may be rebent downwardly and thus lhold the envelop in a closed position. It is also obvious that the plate Q9 and the tongue 32 may be formed from single blank sections of metal so that the same can be cheaply manufactured and also readily attached to the envelop. It will also be evident that when the envelop is folded and the top flap Q3 is folded along the central longitudinal crease 35 that the end Atongues' 2T will fold inwardly and engage in the pockets formed b v the inclined folding lines 2l in the side flaps so as to retain the envelops in shape when they are compactly folded for shipment and in which ease they will occupy a, minimum amount of space.

lilhatis claimed is:

Lil-in envelop formed of a blank comprising a front portion ano a baclt portion` a bot-torn portion connecting said front' and back portions and having integral side tongues, side flaps formed with the back portion and having supplemental `liaps secured tothe front portion. said side tongues being secured to said naps to form a box like receptacle. a top flap carried by the .back port-ion and having side tongues adapt-- ed to lie adjacent said side flaps and a clos ingtiap carried by the top flap and secured to the front portion.

2. An envelop formed with front andV back portions of similar shape and connected -at the lower edges by a bottom portion. having a central longitudinal folding crease, Ysaid bottom portion having end tongues foldable thereon and having said crease extending therei'nto, side Haps formed with the back portion and having attaching portions romero at their free ends secured tothe inner'facc of the front portion, said side flaps having central vert-ical foldingcreases lying coin-- in Contact, said side flaps also having in-y clined folding creases between their upper corners and their central creases to fold downwardly and outwardly, a cover flap carried by one of said port-ions and having a central folding crease permitting it to extend vinto said. downwardly folded portions of the side flaps and a sealing flap for the envelop.

An envelop formed of a blank comprising a front. portion and a back portion, a bottom portion connecting said front and back portions and having integral side tongues., side flaps formed with the back portion and having supplemental flaps secured to the front portion, said side tongues being secured exteriorly'to the lower portions of said flaps to form a box like receptacle. a top flap carried by the back portion and having side tongues secured exteriorlyto the upper portions of said side flaps and a closing flap carried by the top flap and secured to the front portion.

il.. An envelop formed with front and back portions o similar shape and connected at the lower edges by a bottom portion having acentral longitudinal folding crease,

said bottom portion having end tongues foldable thereon and having said crease eX- tending thereinto, side flaps formed with the back portion and having attaching portions at their free ends scoured vertically to the inner: face of tire front portion at its outer edges, said side flaps having central vertical folding creases in the end tongues when the latter are secured to the outer faces of the end aps to permit the envelop to collapse with the4 front and back portions in contact7 said side flaps also having inclined folding creases between' their upper corners and their central creases to fold downwardly and outwardly. a cover flap carried by one of said portions and having a cent-ral folding crease permitting it to extend4 into said downwardh7 folded portions of the side flaps and between the front and back portions and a sealing flap for the envelop.

ln testimony whereof, I affix my signature, in presence lof two witnesses.
